Know your bird's sex — from a single feather.
Fast, reliable and completely non-invasive DNA sexing. Send a feather, a drop of blood or an eggshell and get a clear result in 2–3 working days.
The safe way to determine your bird's sex.
Non-invasive
No anaesthetic and no surgery — just a small sample you collect yourself.
Any age, any season
Works for birds of any age and at any time of the year.
No stress
Your bird stays at home — there is no transport or handling stress.
Reliable
A proven method, with every result double-checked against our database.
From sample to result in four steps.
Sex is determined from the sex chromosomes: males carry two identical Z chromosomes (ZZ) and females a Z and a W (ZW). In the analysis a male shows a single DNA band and a female shows two — compared against STAB VIDA's database of known species and sexes.
Collect the sample
A few growing feathers, a drop of blood, or an eggshell.
Send it to the lab
In a sterile bag or tube, together with the order form.
DNA analysis
We extract the DNA and read the Z/W sex chromosomes.
Get your result
A clear male/female result in 2–3 working days.
Which sample can you send?
Feather
4–5 feathers in early growth, collected in a sterile bag.
Blood
3–5 drops from a nail prick, or ~0.1 ml on filter paper or in an alcohol tube.
Eggshell
The whole shell, collected within 24 hours of hatching, in an alcohol tube.
Over 1,000 species tested.
We have determined the sex of more than a thousand bird species and keep growing our reference database.

Frequently asked questions.
How long does it take?
Results are delivered within 2–3 working days from the moment we receive your sample.

Which birds can be tested?
Over 1,000 species. If yours is not yet in our database, we test it from a master sample at no extra cost.
How reliable is it?
The method is well established and every result is double-checked against our species database before it is issued.
